The solar collector comprises a plurality of direction adjustable elongated parabolic reflectors arranged side by side. Along the focus of the reflectors are tubes for a heat collecting medium. The tubes are to be connected to heat exchangers or the like. Each reflector consists of reflector wall portions movably connected to each other and operable from an open parabolic reflector position to a non-reflector position entirely enclosing the tubes, and forming a relatively flat structure resembling a venetian blind slat.
